Abstract
A device for applying compressive pressures against a patient's limb from a source of pressurized fluid. The device has an elongated pressure sleeve for enclosing a length of the patient's limb, with the sleeve having a plurality of laterally extending separate fluid pressure chambers progressively arranged longitudinally along the sleeve from a lower portion of the limb to an upper portion of the limb proximal the patient's heart relative to the lower portion. The sleeve has a plurality of laterally extending ventilation channels located intermediate different pairs of adjoining compression chambers and having openings for facing the patient's limb. The sleeve also has a connecting channel extending along the side of the pressure chambers and communicating with the ventilation channels. The device also has a control assembly for intermittently inflating and deflating the pressure chambers and for passing air into the ventilation channels to ventilate the patient's limb through the openings.
